1.数字输入/输出(Digital Input/Output): 可以配置引脚为数字输入或数字输出。数字输出用于控制外部设备,数字输入用于读取外部信号。 2.模拟输入(Analog Input): ESP32的某些引脚支持模拟输入,可以读取0到3.3V范围内的模拟电压。 3.PWM输出(Pulse Width Modulation): 一些引脚支持PWM输出,用于模拟输出,例如
/* - DMA2_Stream0 channel2 configuration */ /* - Configure ADC Channel7 pin as analog input */ /* - Configure ADC3 Channel7 */ ADC3_CH7_DMA_Config(); /* Start ADC3 Software Conversion */ ADC_SoftwareStartConv(ADC3); while (1) { ADC3ConvertedVoltage = ADC3ConvertedValue *3300/0xFFF...
ESP32S3 Sense接入百度在线语音识别 前言本文使用Seeed XIAO ESP32S3 Sense开发板接入百度智能云实现在线语音识别。自带麦克风模块用做语音输入,通过串口发送字符“1”来控制数据的采集和上传。步骤概括 在百度云控制端选择“语音识别”并创建应用获取API Key和Secret Key获取token 采集音频数据,将数据打包成规定的格式...
Since all GPIO pins of the XIAO ESP32S3 are assigned their own functions, we do not have a GPIO configured for the battery pin. this means that we cannot get the battery voltage at the software level by reading the analog value of one of the GPIOs. If necessary, you can consider conn...

- Connecting gas Sensors: Connect the four gas sensors to the DFRobot ADS1115 using the VCC, GND, and ADC pins. The sensors should be connected to the analog input channels A0 to A3 on the ADS1115 (Connection order A0-A3: H2S, VOC, Odor, SMOKE). The K10 is connected to the ADS111...
Has anyone measured the SPI ethernet throughput with S3 yet? Preferably with KSZ8851.. I may have project where ESP32 RMII can't be used because of high pin usage while not needing super-fast ethernet anyways, also builtin USB-JTAG saves other 4 pins, so the S3 seems to be a good fi...
1. 前言围绕ESP32S3 Sense接入语音识别+MiniMax模型对话展开,首先串口输入“1”字符,随后麦克风采集2s声音数据,对接百度在线语音识别,将返回文本结果丢入MiniMax模型,进而返回第二次结果文本,实现语言对话文…
